IMPROVEMENT lN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 167,566, datedSeptember 7, 1875; application filed January 11, 1875.

To all whom it may concern:

Be it known that we, SEYMOUR RAYMOND and JOSEPH CAMPBELL, of Middletown,Dauphin county, Pennsylvania, have certain Improvements inHeating-Stoves, of which the following is a specification:

The object of our invention is to so construct a stove that it can bereadily converted from a directdraft into an airheatin g stove.

This object we attain in the manner which we will now proceed todescribe, reference being had to the accompanying drawing, in which-Figure l is a vertical section of sufficient of the stove to illustrateour invention; Fig. 2, a sectional plan 011 the line 1 2; and Fig. 3, asectional plan on the line 3 4, Fig. 1.

That part of the stove which contains the combustion-chamber consists ofthe external flaring casing A and internal flaring casing B, and to theformer is attached the cylindrical casing A, within which is acylindrical casing, B, attached to the upper edge of the casing B, andclosed at the top a by a suitable cover. From the top a'is suspended themagazine D, the latter having at the top lateral openings b for thepassage of gas. At the rear of the stove, between the magazine D and thecasing B, is formed a vertical flue, E, open at both ends, and providedwitha damper, G, on opening which the products of combustion can take adirect course upward through the said flue to the exitpipe. The rearportion ofthecasing B of the combustion-chamber is free from openings,but in the front there are doorways .90 extending through both casings,the doorways beingfurnishedwiththeusual micadoors. The inner casing B ofthe combustion-chamber is cast in one piece with the flanges m, Fig. 4,

which form the sides, top, and bottom of the doorways, the junction ofthe outer with the inner casings being at the outer edges of theseflanges, so that the joints are beyond the range of the products ofcombustion, which cannot, therefore, escape at said joints.

Air is admitted to the space between the two casings through suitableapertures at or near the lower edge of the same, and, passing upward, isbrought into intimate contact with the heated casings B and B, the hotair being permitted to escape into the room containing 7 the stove, orbeing conveyed through suitable pipes to upper rooms.'

In order to insure thecontact of the heated gases with the entiresurface of the casing B it is only necessary to close the damper G, whenthe gases will be compelled to circulate round the magazine beforeentering the flue E, down which they then pass to the pipe E, therebytraversing and effectually heating the casing B and the air in contacttherewith.

On turning the damper the gases will find a direct outlet to theexitpipe.

We claim as our invention In a heating-stove, the combination of amagazine, -I), cylinder B, vertical pipe E, between the cylinder andmagazine, and open at both ends, horizontal out-let F, communicatingwith the pipe E, and the valve D, in the pipe below the outlet, allsubstantially as and for the purpose set forth.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
